Food allergies are becoming more prevalent in today’s world, with over 32 million people suffering from different types of food allergies globally.

Food allergy is an abnormal immune response to specific food substances, which may cause mild symptoms such as hives or severe anaphylaxis, which may be life-threatening. Some of the most common types of food allergies include:.

1. Peanut Allergy

Peanut allergy is one of the most common types of food allergies, affecting approximately 1.6 million Americans.

Those who suffer from peanut allergies have an allergic reaction to the proteins found in peanuts, which can cause severe symptoms such as difficulty breathing, anaphylaxis, and even death in extreme cases.

2. Tree Nut Allergy

Tree nut allergy is another common food allergy that can cause severe reactions. Tree nuts such as almonds, cashews, hazelnuts, pecans, and walnuts are common culprits.

Symptoms of a tree nut allergy can be mild, such as hives or an itchy mouth, or severe, like anaphylaxis. It’s important for those with a tree nut allergy to avoid nuts and products that may contain them.

3. Shellfish Allergy

Shellfish allergy is also very common, affecting approximately 7 million Americans. Shellfish such as shrimp, crab, and lobster are high in allergens and can trigger severe allergic reactions.

A shellfish allergy can cause symptoms ranging from hives and itching to anaphylaxis, which is a severe, life-threatening reaction.

4. Milk Allergy

Milk allergy is a common allergy that affects infants and young children but can also occur in adults. Those with a milk allergy are allergic to the proteins found in milk and can exhibit symptoms such as hives, vomiting, and diarrhea.
